Development of the Protection Coat for Metallic Structures Based on the Intercalated Graphite Compounds

The practicability of introducing a synthesized graphite compound, intercalated with oxygen, into the protection coat is grounded. The composition and the method of manufacturing a protection coat based on the oxidized graphite, which does not require preliminary preparation of the metal structures surface before welding with an open arc, have been developed. The effect of the oxidized graphite content in the composition of the protection coat on its thermal stability and thermal expansion coefficient is analyzed. The main technological characteristics of the developed protection coat have been investigated and their compliance with the basic criteria for constructing protection coats has been confirmed.

Phase evolution of electrochemically potassium intercalated graphite

The phase evolution behavior of electrochemically K-intercalated graphite is examined by operando X-ray diffraction and first-principles calculations in comparison to that of a Li system based upon optimizing the graphite electrode and electrolyte conditions for analysis.
